Sri Lanka is part of the largest exposed Neoproterozoic high-grade metamorphic terrain in the world and was at a central location in Gondwanaland. It has an almost 2 billion year long record of magmatism, sedimentation, deformation and metamorphism. The THICNES (The Highland-Vijayan Contact zone experiment in Sri Lanka) is a mid to long-term program focussing to reveal the properties of crust and upper mantle of Sri Lanka and to model and quantify the underlying geodynamic processes. In 2016 and 2017 a temporary broadband seismic network was installed in the island to observe local, regional and teleseismic earthquakes.
